Java如何操作Android的adb shell
Android在操作一些命令的时候需要进入到adb shell，然后才可以执行其他的命令，那么如何做到这一点呢？就要把adb shell按一个Process执行，然后再去操作这个Process的输入和输出流。
代码如下：
这段代码是操作 cmd.exe的
try {
Process process = Runtime.getRuntime().exec("cmd.exe");
OutputStream outputStream = process.getOutputStream();
final InputStream inputStream = process.getInputStream();
new Thread(new Runnable(){
byte[] cache = new byte[1024];
public void run() {
System.out.println("listener started");
try {
while(inputStream.read(cache)!=-1){
System.out.println(new String(cache));
}
} catch (IOException e) {
//e.printStackTrace();
}
}
}).start();
outputStream.write(new byte[]{'d','i','r','\n'});
//inputStream.
int i = process.waitFor();
System.out.println("i=" + i);
} catch (Exception e) {
e.printStackTrace();
}
这段代码是操作Android adb shell 的
try {
Process process = Runtime.getRuntime().exec("adb shell"); //adb shell
final BufferedWriter outputStream = new BufferedWriter(newOutputStreamWriter(process.getOutputStream()));
final BufferedReader inputStream = new BufferedReader(new InputStreamReader(process.getInputStream()));
//这里一定要注意错误流的读取，不然很容易阻塞，得不到你想要的结果，
final BufferedReader errorReader = new BufferedReader(new InputStreamReader(process.getErrorStream()));
new Thread(new Runnable() {
String line;
public void run() {
System.out.println("listener started");
try {
while((line=inputStream.readLine()) != null) {
System.out.println(line);
}
} catch (IOException e) {
//e.printStackTrace();
}
}
}).start();
new Thread(new Runnable() {
final BufferedReader br = newBufferedReader(new InputStreamReader(System.in));
public void run() {
System.out.println("writer started");
String line;
try {
while ((line =br.readLine()) != null) {
outputStream.write(line + "\r\n");
outputStream.flush();
}
} catch (IOException e) {
//e.printStackTrace();
}
}
}).start();
int i = process.waitFor();
System.out.println("i=" + i);
} catch (Exception e) {
e.printStackTrace();
}
}
